The Ultimate Beginner's Guide To Learning SQL - From Retrieving Data To Creating Databases! Structured Query Language or SQL (pronounced sequel by many) is the most widely used programming language used in database management and is the standard language for Relational Database Management Systems (RDBMS). SQL programming allows users to return, analyze, create, manage and delete data within a database – all within a few commands. With more industries and organizations looking to the power of data, the need for an efficient, scalable solution for data management is required. More often than not, organizations implement a Relational Database Management System in one form or another. These systems create long-term data “warehouses” that can be easily accessed to return and analyze results, such as, “Show me all of the clients from Canada that have purchased more than $20,000 in the last 3 years.” This “query,” which would have taken an extensive amount of hands-on research to complete prior to the use of database, can now be determined in seconds by executing a simple SELECT SQL statement on a database. SQL can seem daunting to those with little to zero programming knowledge and can even pose a challenge to those that have experience with other languages. Most resources jump right into the technical jargon and are not suited for someone to really grasp how SQL Actually Works. That’s why we created this book. Our goal here is simple: show you exactly everything you need to know to utilize SQL in whatever capacity you may need in simple, easy to follow concepts. Our book provides Multiple Step-by-Step Examples of how to master these SQL concepts to ensure you know what you’re doing and why you’re doing it every step of the way. This book will allow you to successfully go from knowing absolutely nothing about SQL to being able to quickly retrieve and analyze data from multiple tables. Step-by-step we will Walk You Through the Fundamentals of Understanding How a Relational Database is Structured to how to execute Complex SELECT Statements to return large datasets from your database.

Build a core level of competency in SQL so you can recognize the parts of queries and write simple SQL statements. SQL knowledge is essential for anyone involved in programming, data science, and data management. This book covers features of SQL that are standardized and common across most database vendors. You will gain a base of knowledge that will prepare you to go deeper into the specifics of any database product you might encounter. Examples in the book are worked in PostgreSQL and SQLite, but the bulk of the examples are platform agnostic and will work on any database platform supporting SQL. Early in the book you learn about table design, the importance of keys as row identifiers, and essential query operations. You then move into more advanced topics such as grouping and summarizing, creating calculated fields, joining data from multiple tables when it makes business sense to do so, and more. Throughout the book, you are exposed to a set-based approach to the language and are provided a good grounding in subtle but important topics such as the effects of null value on query results. With the explosion of data science, SQL has regained its prominence as a top skill to have for technologists and decision makers worldwide. SQL Primer will guide you from the very basics of SQL through to the mainstream features you need to have a solid, working knowledge of this important, data-oriented language. What You'll Learn Create and populate your own database tables Read SQL queries and understand what they are doing Execute queries that get correct results Bring together related rows from multiple tables Group and sort data in support of reporting applications Get a grip on nulls, normalization, and other key concepts Employ subqueries, unions, and other advanced features Who This Book Is For Anyone new to SQL who is looking for step-by-step guidance toward understanding and writing SQL queries. The book is aimed at those who encounter SQL statements often in their work, and provides a sound baseline useful across all SQL database systems. Programmers, database managers, data scientists, and business analysts all can benefit from the baseline of SQL knowledge provided in this book.
